Set caret location to a specific line in a text control

I have an input screen where the user types into an SWT Text control. As the user types I take the text, process it and show it in a separate read_only result text control. The length of the result text might be several characters longer than the input text.
I would like to position the resultant text control display so that it always shows the line where the user is currently typing in the input control.
I can get the input caret line using ivTextInput.getCaretLineNumber(), but there is no corresponding method to set the caret line number.
I can set the position of the caret in the result using ivTextResult.setSelection(ivTextInput.getCaretPosition()) but the processing I do on the input text might "push" the result text down to the point where it is not visible without scrolling.
Ideally the result text display would marry-up with the input text display so that what/where the user types always lines up with the result text.
I have tried keeping track of the extra characters the processing adds, but the user can add text anywhere in the text control, and the resulting mess is un-usable, plus the way SWT text control handles new lines throws calculations off.

Text has a setTopIndex method to set the line visible at the top of the control:
public void setTopIndex(int index)

Codename One: How to display the contents of entire properties page

I have a properties page that looks like this
property1=value1
property2=value2
property3=value3
property4=value4
And my plan is to be able to create a page in my app that will display these values and allow the user to change and save them.
The way that I thought I would do this is to create a method that will iterate through the file and populate a text control with the data.
I am using the 'propertyNames' function explained here https://www.codenameone.com/javadoc/com/codename1/io/Properties.html
Unfortunately when I use this, all that is listed are the properties and not the values
Is there a way to show the entire contents of the properties file?
The other way I was thinking about doing it is to create a list of buttons that correspond to the keys - so one button for each key [with the key name as the button label] - and then when the user clicks on the button it displays the key value in an editable text box, and a save button that writes it back to the file.
Is this possible?
Thanks

propertyNames gives you all the keys, then you can retrieve the value of each get key using getProperty:
for(String key:props.propertyNames()){
String value = props.getProperty(key);
output += key+"="+value+"<br/>"; //however you output your stuff
}
After letting the user set new values, you can set them using setProperty(key, newValue).

Filling out a web form automatically with a text file

I request a web page in the browser and I should fill out the text boxes it has. They are too many text boxes and it takes too mush time too fill them and the result of this latency is an expired page. I have written those inputs in a text file (each line for each text box). I want to write a program that when it is running, it fills out the form and I just click the submit button of the website.
The form is something like the following image:
I have a form which somehow looks like the following image:
I searched a lot to find a way to fill out the text boxes automatically in C# but did not find anything. My question is that is there anyway to set the values of these text boxes in C# and send them back to server?

You can write a json object, then a javascript function that iterate that json and figure out by each value the selector of the correct input to use and set the correct value.
Then when the page open, use the dev console.
paste the json object, paste the function.
Run the function and the form should get fill out.

how to change the jasper report textfield markup property value dynamically in java

I wanted to change the text field markup property value of jasper report in run time of java application.
Without modifying/recompile the jasper file.

For current feature, its impossible to change textfield markup value in java application. But there is a trick that u might want to try.
First, textfield markup have 4 fixed options which is none, rtf, html, styled. U can pass parameter from java app to change markup property value let say markupValue.
In Jasper, u need to create 4 different textfield with different markup value as i mention above. At each Texfield Print When Expression, u need to compare value parameter markupValue that u pass from java app.
$P{markupValue}.equals("rtf") will display textfield with markup value rtf and so on.

How to bind a Class object properties into JFrame's JTextfileds

I am developing a Java GUI form using JFrame including many text boxes in it.
Now to save value of these text boxes i need to take all the value from text boxes separately, and then have to bind it with object using its class constructor..
But instead of this i want to automatically bind all text boxes value into class object so i can simply get the object which has all text box's value already bound..
Pleas help me if is there any framework or any other day to do the same..
Thanks in advance
